Specicaton of Letters Patent.

Patented March 2, 1909.

Application led April 18, 1908. Serial No. 427,825.

To all whom it may cof/wem:

Be it known that I, AMBnosE BARKLEY, a citizen of the United States, residing at Pipestone, in the county of Pipestone and State of Minnesota, have invented a new and useful Cultivator, of which the following is a specification.

The invent'on relates to improvements in cultivators.

The object of the present invention is to improve the construction of cultivators, and to provide a simple and comparatively inexpensive cultivator, capable of straddling a row of plants to cultivate the soil in the space between the same and the adjacent rows, and adapted to permit the driver to occupy a position directly above the row of plants straddled by the machine, whereby the soil at cach side of the straddled row of plants will be in full view of the driver and thereby enable him to cultivate the same to greater advantage.

TWith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacriiicing any of the advantages of the invention.

In the drawings z-Figure 1 is a perspective view of a cultivator, constructed in accordance with this invention. Fig. 2 is a detail sectional view, taken longitudinally of the central beam of one of the gang frames. Fig. 3 is a transverse sectional view, illustrating the construction of the adjustable braces for connecting the side beams with the central beam. Fig. 4 is a detail transverse sectional view, illustrating the manner of mounting the transverse lever of the draft mechanism. Fig. 5 is a reverse plan view of the front portion of the frame of the machine, showing the arrangement of the neck yoke and illustrating the manner of connecting the longitudinal connecting rods with the draft beams of the frame of the cultivator. Fig. 6 is a detail sectional view of the hinge connection between the longitu dinal connecting rods and the front ends of Fig. 7 is a detail view of one of the angularly disposed connecting leand pointed out in the claims said shovels vers. Fig. 8 is a similar view of one of the hand levers for actuating and locking the connecting levers. Fig. 9 is a detail view of the foot of the central shifting lever for moving the gangs of cultivating devices transversely of the machine.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

The frame of the cultivator includes a pair of forwardly converging draft beams l, secured together at their front ends and connected at an intermediate point by a transe verse bar 2, inter osed between the draft beams and suitab y secured to the same. The rear ends of the draft beams are supported upon and secured to an arched axle 3, provided at the lower ends of the sides of its arched portion with laterally projecting journals, on which are mounted carrying wheels 4. The main frame is braced by inclined rods 5, extending upwardly and forwardly from the lower portions of the sides of the arched portion of the axle to the forwardly converging draft beams and secured to the lower face of the same in advance of the arched axle.

The machine, which is adapted to straddle a row of plants, is equipped with opposite gang frames provided with blades or shovels adapted to cultivate the surface of the soil at opposite sides of the row of plants straddled by the machine. Each gang frame is composed of a short central longitudinal plow beam 7 and rearwardly diverging side cams 8, pivotally connected at their front ends with the central beam by means of upper and lower plates 9 and l0, secured to the up er and lower faces of the central beam an projecting laterally therefrom and forming spaced ears or portions, between which the front ends of the side beams are pivoted by vertical bolts l1, or other suitable fastening devices. The rear end of the central beam is located in advance of the adjacent side or carrying wheel l of the cultivator, and the rear portions of the side beams extend rearwardly beyond the rear end of the central beam and are located at the inner and outer sides of the said wheel. These beams are provided with standards 12, to which the or blades 6 are secured, and any desired number of blades or shovels may be provided, as will be understood. The pivoted side beams are adjustable toward and from the central beam to arrange the cultivating devices to correspond to the width of the space between the rows, and they are secured in their adjustment by transverse connecting bars 13, having overlapped proximate ends and pivoted at their outer ends by bolts 14 to the side beams 8. The inner overlapped portions of the connecting bars 13 are provided at intervals withy perforations 15 for the reception of a vertical bolt 16, which. also pierces the rear end of the central beam 7. By adjusting the side beams toward and from the central beam, the cultivating devices may be arranged to clear the plants, and to cultivate the soil between the rows without injuring the plants.

The gangs of the cultivating devices are connected by an arch 17, andare adjustable toward and from each other to arrange them the desired distance from the plants and to position them to suit the width of the rows. The lower ends of the arch are provided with laterally projecting arms or portions 18, having perforations and secured to the inner side beams of the gang frames by bolts 19, or other suitable fastening devices.. This adjustment of the gangs of cultivating devices toward and from each other, and the indi vidual adj ustment. of the beams of each gang. frame, enable the cultivating devices to be properly positioned to correspond to the width of the rows.

The front ends of the gang frames are connected with the front ends of thel draft beams by longitudinal connecting rods 20, converging forwardly from the gang frames and having their rear ends 21 secured to the central beams at` the inner faces thereof. The connecting bars are bent laterally and extend inwardly from the front ends of the central beams, and the front ends of the connecting rods are pivoted by a pin 22, or other suitable fastening device to a leaf 23. of a hinge 24, having its other leaf 25 secured to the lower faces of the draft beams 1 at the connected front portions thereof. The rear leaf 23. is free and permits the longitudinal connecting rods to swing upwardly and downwardly to raise and lower the gangs of the cultivating devices, and the pivot or pin 22 permits the connecting bars to swing transversely when the gangs of cultivating devices are adjusted toward and from each other.

The gangs of cultivating devices are ad.- justed simultaneously in a direction transversely of the cultivator by meansof a central operating lever 26, fulcrumed intermediate of its ends on the' arched axle at the center thereof by means of a suitable pivot 27 and extending in advance and in rear of the said axle. The front portion of the central longitudinally disposed lever 26 is bentdownward, and is provided with a laterally projecting foot 28, consisting of a plate or member having slotted or bifurcated ends 29 receiving the sides of. the connecting archy 17.

The foot, which is interposed between the sides of the connecting arch, slidably receives the same and ermits the gangs of cultivating devices to lib raised and lowered independently of the central shifting lever. The central shifting lever enables the operator to cultivate the soil as closely as desired to either side of the row of plants straddled by the machine by shifting the gangs laterally of the row of lants. The central longitudinal adjusting ever is located between a pair of seat standards 30. The sea-t standards 30 are secured at their front ends tothe inner edges of the rear terminals of the draft beams 1,v and they extend rearwardly from the frame of the cultivator and support a rear seat 3-1 for the accommodation of the driver. The arrangement of the seat in this position permits the driver tol sit directlyabove the row of plan-ts straddled by the machine, and he is in a position to see the character of the work performed by thegangs of cultivating devices at each side of the plants. This will enable the driver to perform better work than when occupying ar position between two rows of plants. The machine is.v also equipped with foot rests 32,v consisting of approximately L-shaped piecesrigid with the sides of the arched portion of the axle and extending rearwardly therefrom, as clearly shown in Fig. 1 of the drawings.

The gangs of cultivating devices are raised and lowered by means of foot levers 33 and hand levers 34. The foot levers, which arefulcrumed at their front ends 35` on. the axle at the sides of the arched portion, extend soV rearward-ly therefrom and are connected near their rear ends by chains 3.6, or other suitable flexible connectionswith the rear ends of angularly disposed levers 37, fulcrumed at an intermediate point on the frame of the 'machine at opposite sides thereof, and connected at their front ends by chains 38 with the gangs cf cultivating devices. The angularly disposed levers, which converge rearwardly, are pivoted between upwardly extending ears or arms 39; mounted on a rear transverse bar 40, which is secured to the draft beams of the main frame near the rear ends thereof. The chains- 38, which extend downwardly 'from the front ends of the longitudinal levers, are connected with the gangframes by plates or members 41, secured to thel rear ends of the central beams 7 by the bolts 16, and. provided at their front ends` with eyes, which arelinked into rings carried by the lower ends of the chains. Any other suitable means, however, may the fron-t ends of. the angularly disposed levers withl the gang frames. The rear terminals of the foot leversf are bent laterally and extend inwardly and are adapted to be engaged by the feet of the operator.v Nhena either. of the foot levers. isi depressed, the:

angularly disposed lever with which it is connected lifts the gang frame at that side of the machine.

rlhe hand levers 34, which extend rearwardly beyond the connecting levers, are fulcrumed at their front ends with bolts 42, which pivot the connectinglevers to the ears 39, and the said hand levers are provided at points intermediate of their ends with laterally projecting hoch-shaped lugs 43, arranged to engage the upper edges of the conneotinglevers attherearendsthereof, whereby the rear arms of the connecting levers are swung downward when the hand levers are depressed. The hand levers are also provided at their outer sides with laterally projecting studs 44, adapted to engage perforations 45 of vertical standards 46, mounted on the main frame, and having horizontal plates or portions secured to the upper faces of the draft beams at the rear ends thereof. The studs of the hand levers are adapted through their engagement with the standards to lock the gangs of cultivating` devices against downward movement. The foot levers are adapted to be operated independently of the hand levers to lift the gangs of cultivating devices from the ground, and when the foot levers are permitted to swing upward, the downward movement of the cultivating devices will be limited by the hand levers through their engagement with the connecting levers.

The cultivator is designed to be actuated by a pair of horses, hitched to draft elements, which, in the accompanying drawings, are in the form of whiflletrees 46"-, connected with substantially vertical levers 47, pivoted at their lower ends to the gang frames at the front ends of the central beams and having reduced rounded upper portions 48, which are arranged in perforations 49 of a transverse lever 50. T he rounded upper portions 48 are slidable in the openings of the transverse lever to permit the gang frames to be raised and lowered independently of the transverse lever. The transverse lever 5G, which extends across and projects beyond the forwardly converging draft beams, is centrally pivoted to the transverse bar 2 by a bolt 51. Any other suitable means can be employed for pivotally connecting the upper ends of the substantially vertical lever with the terminals of the transverse lever 50, and the said vertical levers are provided at intermediate points with a plurality of perforations 52 for the adjustment of the draft elements or whiiiietrees. The front ends of the central beams 7 are equipped with plates 53, provided with ears between which the lower ends of the upright levers are pivoted. rlie draft animals are connected with the main frame by means of a neck yolre 54, located at the front ends of the forwardly converging l means of a plate or member 55, having a forwardly extending arm or portion 56, provided with a terminal pivot 57, which pierces the neck yoke.
